Be sure and change "[EMAIL PROTECTED]" on line 20 to something
appropriate for you.
What it does is every 5 minutes it looks at all the running java
processes looking for WebObjects applications. It uses the same
mechanism as wotaskd to "ping" the app via curl. If the app doesn't
respond within 10 seconds, it increments a counter. If the counter
counts up to 6, it starts sending out a warning email. If it counts
up to 12, it does:
killall -9 hsdbd; jstack $pid
to grab a stack crawl, then kills the app and emails the stack
crawl. You have to run this script with sufficient privileges on all
of your app servers.
